Actually, I did see today that they were showing off an EDF Portable V2 at the Tokyo Game Show as well (]link to video).

From the video it looks like they might actually be porting a modified version of the old PS2 EDF2 that never came out in the west, so that's a brand new experience for me. Woohoo! (assuming it comes to the west this time since the first EDF Portable was one of the best sellers on the vita digital store...)
